i Application filed August 10, 1927'. Serial No. 211,955

This invention relates to coin handling mechanisms and particularly to coin payers and changers.

The main objects of this invention are to provide a coin handling mechanism having an improved form of ejector; to provide an improved form of ejector for ejecting the lowermost coin from a magazinewherein the coins are stacked vertically; to provide. an ejector of this kind havrnglinproved means for supporting the com being ejected substantially parallel to the other coins until it leaves the v magazine; and to provide supporting means'of this kind which will produce a min imum amount of friction on the lowermost coin in. the stack on the retraction ofthe ejec tor. 7

An illustrative embodiment of this invention is shown in the accompanying wherein I I Figure 1 is a transverse vertical section showing part of a coin payer and changer to which this invention is applied.

Fig. 2 is an enlarged detail in'section'of an tion with various types of coin handling mechanisms but, in the specific form herein shown, it is applied to a coin payer or changer.

Inasmuch as this invention relates particularly to'the ejector, certain parts of the ma chine not relating thereto and believed to be drawings.

In the form shown, the coin payer and ing 6 for receiving the tray 4;. :EXtending; upwardly through the casing, is a partition 1 7, having a pluarlity of slots 8, through which drawing,

line 3+3 of plurality=of slots 16 arranged to providethe ejectors extend for engagement with the 1 lowermost coins in the-tray 41.

The chute 2 is corrugated, as shown at 9, in

order to minimize the'bearing surface of the chute which is presented to the falling coins. At the lower end of the chute, is arranged a suitable coin receiving cup, not shown. The tray 4 comprises a battery of tubular ly secured to a back plate 11, which may be detachably secured-to the casing in any suitable manner. The tubular magazines 10 are open at the front side, as shown at 12, permitting insertion of the'operators fingers to-facilitate' loading of the tray with coins. 'The magazines vary in size'to accommodate coins of different denominations. end of each magazine, the edges of the tubular wall adjacent the opening 12 are struck out to provide lugs 13 arranged to define an magazines 10 arranged side by side and'rigid- At the lower utlet opening 1 1 through which t coins I are ejected.

The lower end of the back plate 11 is bent along theentire tray to provide a bottom for the magazines. Formed in the shelf 15, is a guideways for the ej ectors 5, which are thereby guided through substantially the centers of the outlet; openings 14. V r

In the form'shown, each of the ejectors 5 comprises an arm, preferably a sheet metal stamping which is resiliently suspended ad jacent its forwardend by a spring '17 sup ported by a hanger'18 which extends through the uper rear part-of the casing 1.. The lower to form a transverse shelf 15 which extends ends -ofthe springs 17 aresecured to lugs 19 formed on the ejector arms 5.

The ejector arms are selectively actuated by a plurality of manually operated keys which '5 i are not shown but which are-well understood "in the. art. unnecessary to a complete understanding of the invention have been omitted from the "Formed adj acent the forward end of each position so as to position the shoulder 20 rearwardly of the lowermost'coin, as shown in Fig. 1. If desired, the shoulder 20 maybe formed so as to engage more than one coin at each operation.

Theextremity of the finger 21 projects upwardly to provide a tip 22 which is adapted to en agefthe tween the shoulder and tip 22 is slightly greater than the radius of the coin to be ejected. so

Q it In operation, the ejectors 5 are operated forward movement of any ejector, the shoulderv20- moves diorwal'dly through the respec tive slot 16 in engagement with the rear edge or the coin. The tip 22' engages the lower fac'eof the coin for holding thecoin substantially parallel to? the other coins in the magezine. When the coin reaches the position showninFig. 4, so as to be outofcontact with the shelf 15;a nd the next succcedi-ngcoin, it,

to one side and drops onto-the (chute 2. e stack of coins then drops inthe magazine so asto positionthenext succeeding coin on the shelf 15. Due tothe weightolfithe stack 1 of coins, upon the retraction of the ejector the arm 5 is -moved downward} against the action of-the spring 17, there ycausing the upperedgeof the-arm to slidably engage the lower faceof the-stack. By reason ofitheofiset position of the'fin er'21,the friction between'the-ejector an the stack-0f coins is reduced toe" minimum.
